"Shanghai has mastered the art of layered development," observes urban scholar Professor Chen Wei. "Like a palimpsest, it writes its future without erasing its past - each era's contributions remain visible and valued."

This delicate balancing act faces challenges as climate change pressures increase and global economic uncertainties persist. Yet Shanghai's unique ability to adapt while maintaining cultural continuity positions it as a bellwether for cities worldwide.

As the city prepares to host the 2026 World Expo focusing on "Cities of Harmony," its ongoing transformation offers valuable lessons about sustainable urbanization in the digital age.
